11.1.3 Factors that increase the scan time
When executing the program memory batch transfer by GX Developer, the processing
time shown in Table11.30 is

When the "Diagnose redundant power supply system" checkbox is checked on the
PLC RAS tab of PLC parameter in GX Developer, processing time shown in
Table11.31 is required.

* 1 : Power supply error indicates any of the following.
• Redundant power supply module failure
• Power supply for the redundant power supply module OFF
• Redundant power supply module not mounted
Since the Basic model QCPU, High Performance model QCPU, Process CPU, and Redundant
CPU do not use the program cache memory, processing time required for transferring data from
a program cache memory to a program memory can be ignored.
Since the Basic model QCPU does not execute the redundant power supply system diagnostics,
it is not necessary to be conscious of the processing time.
It is not necessary to be conscious of the processing time during the redundant power supply
system diagnostics in the High Performance model QCPU, Process CPU, and Redundant CPU.
When setting the redundant power supply system diagnostics in the Universal model QCPU,
check the versions of CPU module and GX Developer. (
